if you dont beat the car every day what life expectancy can u get out of the supercharged engine? everyone please respond

My feeling is that it will be hard to damage the engine as long as you run synthetic oil and cover the basics such as good coolant, high octane gas, let it warm up before stressing it and so on. The weakest link will go first, probably the transmission, differential, CV's or whatever. These engines seem capable of handling whatever we throw at them.

If you don't beat on the car, and maintain it properly, you'll get pretty much the same life as you would without the supercharger.

Only difference is when the engine hits say 200k miles, the extra boost is going to be harder on it, and chances of something breaking is greater.

I would suspect that you would decrease engine life, on a well maintained engine, by about 15% - 20%.

So a 200k engine will only go to 160k, oh well....

Yeh.... but the kick in the pants from the extra torque, and that whine of the roots blower makes me want to !

scalbert

100% agreed...

There are always trade-offs but that extra performance is worth it IMO...

I wonder if in some cases, the 6-speed (clutch and various tranny parts) might last longer with someone that had enough clear leverage (power advantage) to resist the urge to smack the car through the gears, use high-rev clutch drops, and generally try to beat the car for every 1/20 of a second.

There might be a few people that might get long life out of the sucker by just driving the higher output setup smoother...

-- just a though or three --

True enough. I've only did a clutch dump once at a dead stop. The chattering and wheel hop made me feel sad on the inside.

It's that type of torque spikes to the engine and drivetrain which really cause you problems. Take a tape measure, and pull out 5 feet. You can lift the tape measure up if you're gentle, jerk it and it folds in two.

Same scenero here, so I agree with you.

Realistically, you're not going to be bagging on it that much anyway. I like it for the extra low RPM torque.
